DESK.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed January 17, 1913. Serial No. 742,667.

To all whom it may concern Be it known that I, WAYNE WILLS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Desks, of which the following is a specification.

The principal object of my invention is to provide a new and improved combined desk and seat for the use of school children.

Another object of my invention is to provide a frame for such a desk.

Other objects of my invention relate to various features and details inwthis connection and all these objects will be understood and appreciated from the following specification 7 and claims taken with the accompanying drawings.

In these drawings I have illustrated one specific embodiment of my invention and I now proceed to describe the same. It will be understood that the invention is defined in the appended claims.

Referring to these drawings-Figure 1 is a general perspective view of my improved desk. Fig. 2 is a perspective view of a modified form of the desk adapted to stand at the front of a row. Fig. 3 is a perspective viewof a modified seat adaptedto stand at the rear end of the row. Fig. 4 is a side elevation of the desk. Fig. 5 is a horizontal secdpwn. Fig. 6 is a section on the line 6, 6 '0 looking in the direction of the arrow. Fig. 7 is a fragmentary perspective view showing one of the feet of the desk. Fig. 8 is a central vertical section. Fig. 9 is a horizontal section on the line 9, 9 pf Fig. 4 looking down. Fig. 10 is an inclined section on the line 10, 10 of Fig. 4 looking in the direction of the arrow. Fig. 11 is a perspective view of various elements ofv the desk structure, the same being" spaced apart without'changing their angular relationshipso as to show more clearly the individual construction of each element.

Referring to the form of the desk shown in Fig. 1, each side frame comprises two tubular members 15 and 17 with their lower ends respectively adapted to rest upon the floor, as designated by 16 and 18. The tubing of which these frame members and other frame members are composed is of the form shown in section in Fig. 5, that is, approximately triangular with the meeting edge portions laid side by side adjacent to each Fig. 4

other, but not secured together. Such tubing may be referred to as open tubing to dis tinguish it from seamless tubing or tubing that will not open along a joint line or seam. A third side frame member 19 having the form shown in Fig. 8 has one end secured between a pair of members 20, which also embrace the upper end of the frame member 17. These two members 20 constitute one part of a hinge carrying the seat "46. The axis of this hinge is the bolt 22 and its movable member is designated 23. This part 23 is a lower extension on the support 24 upon which the seat 46 rests.

.The tubular member 25 has its ends 26 and- 27, respectively, connected to the vertical frame members 15 and 17 respectively.

The connection is made by lapping these ends 26 and 27 beside the doubled edge portions of the tubular members 15 and 17 and welding them by the method of point welding. The adjacent edge portions of the two members 25 and 19 lap at 28, as shown in Figsuti and 8, and these four thicknesses of metal are welded together by the same method. A brace 29 consisting of a plate or web of sheet metal has its edges secured by the same method of welding to-the edges of the tubing 15 and 19. Each of the two pieces 29 has one edge extended and turned in at a right angle to form the lug 30 and the, board 31 is attached by the bolts 32 to these lugs 30.

A piece of sheet metal is stamped to the shape shown in the upper part of Fig. 11,.

as designated 33, and its edges 37 and .38 are respectively welded to the meeting edge portions of the upper parts-of the tubular members 15 and 19. This desk end walh33 has a recess 34 along its lower edge to receive the endof the bottom board 39 to support which the ledge 35 is provided. The

topledge 36"supp"orts the desk board 40.

A piece of sheet metal 41 of the form shown in Fig. 11 and with its edges spreading, slightly apart is welded to the top of the ledge 36 and adapted to engage the correspondingly shaped groove 42 in the under side of the desk top 40. Similar attaching elements 43 are welded to the front faces of .the frame members 19 and are adapted to engage, the grooves 45 in the back 44. of the desk seat. Other similar attaching elements 47 are welded to the seat supports 24 and adapted to engage the grooves 48 in the seat 46. The seat 46 may be pushed back the attaching members 43. Then the desk top '40 is pushed against the back 44 and these two parts are secured together by means of the screws 52.

All the parts of this desk frame that are desired to have rigid relationship to one another are fastened together by the method of point welding. It will be seen that the seat 46 has its pivotal support 22 consider-- .ably in front of its rear edge, thus making it of theso-called automatic type by which the seat may be folded back by pressing against its front edge with the calves of the legs of the user, and on the other hand it may be opened from this closed position by simply sitting on the upturned edge and thus throwing the weight of the body to turn it down to the normal position.

The front desk shown in-Fig. 2 simply replaces the elements 17, 19 and 25 with the single tubular standard 53. The rear seat shown in Fig. 3 omits the frame member 15 and employs a supporting member 54 secured directly at its upper end to the frame member 19. i

In this application I do not claim per se the open tube, herein disclosed, formed of a strip of metal bent into tubular form and having the meeting edge portions of the metal strip formed into a projecting flange, as the same is claimed in my copending application, Serial No.-6l5,775,filed March 20, 1911; but what I do claim in this application is a structure in which the combined advantages of said form of flanged tubing are utilized.

I claim:

1. A structure comprising an open tube formed of a strip of metal, the meeting edges of which are turned outwardly in the form-of a flange, said tube being curved in a plane passing through said flange and substantially bisecting the cross section of said tube, and comprising another member overlapping and secured to the flange of said tu e. i

2. A structure comprising open tube members, said open tube being formed of a strip of metal, the meeting edges of which are turned outwardly in the form of a flange, one or more of said open tube members being curved in a plane passing through said flange and substantially bisecting the cross section of said tube, the flanges of said tube members overlapping and being secured together. y

3. A structure comprising an open tube formed of a strip of metal, the meeting edges of which are turned outwardly in the form of a flange, said tube being curved in a meaeee secured to the flange of said first mentioned open tube.

4. In a school desk and seat, rear members of curved flanged open tubing having their flanges directed forwardly, said rear members extending to the rear of the desk top, forward members of curved flanged open tubing having their flanges directed rearwardlv, said forward members extending upwardly to a point beneath the seat level, cross members connecting and secured to the flanges of said rear and front members, intermediate members curved down ward and rearward from the upper part of said forward members to said cross members and thence upward to the front of said desk top,and a seat hinged at the upper ends of said forward and intermediate members.

5. In a school desk and seat, rear mem* bers of curved flanged open tubing having their flanges directed forwardly. said rear members extending to the rear of the desk top, forward members of curved flanged open tubing having their flanges directed rearwardly. said forward members extending upwardly to a point beneath the seat level, flanged tubular cross members connecting and secured to the flanges of said rear and front members, intermediate members curved downward and rearward from the upper part of-said forward members to said cross members and thence upward to the front of said desk top, said intermediate members consisting of flanged open tubing and the flanges thereof overlapping and being secured to the flanges of said cross members, and a seat hinged at the upper ends of said forward and. intermediate members.

6. In a school desk and seat. rear members of curved flanged open tubing having their flanges 'directed forwardly; said rear members extending to the rear of the desk top, forward members of curved flanged open tubing having their flanges directed rearwardly. said forward members extending upwardly to a point beneath the seat level. tubular cross members having flattened ends overlapping and secured to the flanges of said rear and front members, in-

termediate members curved/downward and their flanges directed forwardly, said rear members extending to the rear of the desk top, forward members of curved flanged open tubing having their flanges directed rearwardly, said forward members extend ing upwardly to a point beneath the seat level, cross members connecting and secured to the flanges of said rear and front members, intermediate members curved downward and rearward from the upper part of said forward members to said cross members and thence upward to the front of said desk top, hinge plates embracing and securing together the upper ends of the adjacent 10 front and intermediate members, and a seat mounted upon said hinge plates.
